This marks the first serious bump in the road for Pryor as he attempts to move from quarterback to receiver. The Browns need to see him in as much live action as they can, and the scrimmage was not only going to be the first time Pryor returned to The Horseshoe at Ohio State, but his first time in live action during training camp.

"Not believed to be serious," Pettine said. "But will still be a little bit of time. It will be at least obviously through the scrimmage."

Pryor did not finish Tuesday's practice, and said after he did not pull or tweak the hamstring. It simply felt tight, he said.

He did not expect to miss practice or the scrimmage, but added it would be better to miss a day or a few rather than a longer amount if he aggravated something.

Pressed on Pryor, Pettine said he couldn't say for sure if Pryor would miss the scrimmage, but added: "I'd probably lean toward the doubtful side."

Whether Pryor appears at all in The Shoe for the first time since he was banned by the university from returningremains to be seen. The Browns have not talked about whether injured players would make the 2-hour trip south, Pettine said. Pryor received a five-year ban in 2011 because he did not talk to the NCAA about possible violations. Ohio State previously announced that Pryor would be welcome as a member of the Browns.

Pryor met with the media Tuesday and said he wasn't pointing to Friday as a benchmark.

"I don't look toward Friday," Pryor said. "I do want to go in The Shoe, obviously, and play. But it's practice and I want to be out there for the first preseason game, the second, third, fourth and the first game of the season.

"That's what I'm preparing myself for."

Pryor's injury is one of several that Pettine called a "frustrating" part of Browns camp. Running backs Duke Johnson (hamstring) and Terrance West (calf) are out, as is rookie H-back Malcolm Johnson (shoulder) and Bowe.
